Problems solved by technology

[0002] Tree diameter is an important factor in tree growth, and plays a pivotal role in tree investigation and tree growth law research. However, the accuracy and convenience of tree diameter measurement methods are still a difficult issue. At present, some measurement methods and devices are still In the relatively backward status, especially the research on the relationship between tree growth factors and the growth mechanism, there is no unified conclusion, which has a lot to do with the accuracy of the measurement and the convenience of the measurement method. Therefore, without destroying Under the conditions of trees, it is of great significance and research value to develop a tree diameter measuring device that is easy to install and measure, simple to operate, and high in precision.

Abstract

The invention provides an automatic measurement device for treewalk growth, which realizes that the real-time growth and growing status of treewalk are monitored in real time by virtue of a wireless network node remote monitoring device. The device comprises a device fixing module and a measurement module, wherein the device fixing module fixes the measurement module on a position of a trunk requiring measuring treewalk variation; the measurement module comprises a linear displacement sensor with a spring, a measuring head pulley, a steering pulley, a guide pulley, a non-elastic fine steel wire, a clamp and a connecting part of the measuring head pulley and the linear displacement sensor with the spring; the non-elastic fine steel wire passes through the steering pulley, the guide pulley and the measuring head pulley, and encloses the position requiring measuring the treewalk; two ends of the non-elastic fine steel wire are clamped by virtue of the clamp; and the treewalk growing variation is determined according to the displacement of the linear displacement sensor with the spring.

Description

technical field [0001] The invention relates to an automatic measuring device for tree diameter growth, which is suitable for application in plantation monitoring, plant growth measurement and research on tree growth law, and particularly relates to a real-time automatic measuring device for living tree diameter growth. Background technique [0002] Tree diameter is an important factor in tree growth, and plays a pivotal role in tree investigation and tree growth law research. However, the accuracy and convenience of tree diameter measurement methods are still a difficult issue. At present, some measurement methods and devices are still In the relatively backward status, especially the research on the relationship between tree growth factors and the growth mechanism, there is no unified conclusion, which has a lot to do with the accuracy of the measurement and the convenience of the measurement method. Therefore, without destroying Under the conditions of trees, it is of gre...
